Two (2) mdrs associated with similar problem are being reported from this account: 2122870-2012-008870-2012-00823. The cause of this event was the kinked wash buffer supply tubing. For more than 80 years, we have been a trusted partner for laboratory. The fse removed three inches of the tubing, primed the instrument fluidics and then performed qc within the customer's established limits. At Beckman Coulter, we are dedicated to advancing and optimizing the laboratory. The fse determined the kinked tubing caused the erroneously elevated results and the failing system check results.

NOTE: Captioning functionality requires use of the WebEx Desktop App. The fse then lifted the wash buffer reservoir and observed that the wash buffer line had been kinked and that no wash buffer was allowed to flow beyond the kink.
The fse observed that there was no wash buffer in the main pipettor line, the wash pump lines, or the wash probe lines. It was noted that the instrument had given several "wash valve/pump motion error" instances and several "crosstalk counts outside limits" errors at the time of the event.
The customer did not indicate there were any sample integrity concerns for the patient samples.Ī field service engineer (fse) was dispatched on (b)(4) 2012, to help resolve the issue for the customer. Per customer supplied data, system checks performed on the date of the event failed to pass within instrument specifications. Qc was performing within the customer's established limits on the date of the event. System checks were passing within instrument specifications the day before the event occurred.
